One of the areas that can see an immediate impact from PCI Express Gen 4 which will first arrive with AMD’s upcoming Ryzen desktop processors is storage, and to that end Phison is not waiting around to show just what we can expect from the first generation of PCIe Gen4 SSDs.

The company’s PS5016-E16 controller was on display at CES in a prototype device, and is powered by a quad-core solution combining two ARM cores with a pair of proprietary CO-X processor cores from Phison. Basic specs from Phison include:
- PCIe Gen4 x4 NVMe
- 8 Channels with 32 CEs
- NAND interface: 800 MT/s support
- DDR4 interface: 1600 Mb/s support
- 3D TLC and QLC support
- Designed with Phison’s 4th Gen LDPC Engine

As to performance, Phison lists sequentials of 4000 MB/s reads and 4100 MB/s writes, while providing a graphic showing CrystalDiskMark results slightly exceeding these numbers. How can Phison exceed the potential of PCIe Gen3 x4 with this early demo? As reported by Legit Reviews Phison is using a Gen4HOST add-in card from PLDA, which “uses a PCIe 3.0 x16 (upstream) to PCIe 4.0 x8 (downstream) integration backplane for development and validation of PCIe 4.0 endpoints”.

The Phison PCIe Gen4 x4 NVMe controller is expected to hit the consumer market by Q3 2019.

Microsemi's Flashtec NVMe SSD controllers are now in production, and as Computer Base reports (Google-translated version of the page available here) these controllers use twice as many PCIe lanes than current offerings with a x8 PCI-E 3.0 connection, and can support up to 20 TB of flash capacity.

"The NVMe controller destined for the professional high-performance segment and work with PCIe 3.0 x8 or two x4 PCIe 3.0. The NVMe2032 has 32 memory channels (and) NVMe2016 (has) 16. When using 256-Gbit flash SSDs can be implemented with up to 20 terabytes of storage."
The 32-channel NVMe2032 boasts up to 1 million IOPS in 4K random read performance, and the controller supports DDR4 memory for faster cache performance. The announcement of the availability of these chips comes just before the start of Flash Memory Summit, which our own Allyn Malventano will be attending. Stay tuned for more flashy SSD news to come!

Plextor announced their first M.2 SSD at CES 2016, and now the M8Pe series is officially set for a release this month. Computer Base (German language) had a chance to preview the new drive, and supplied a detailed look at the M.2 version (this is model M8PeG, and the version with a riser card is M8PeY).

Even the M.2 form-factor version of the SSD includes a heatsink, which Plextor warns creates incompatibility with notebooks as the M8PeG is 4.79 mm in height with the heatsink in place.
Specifications for the drives are as follows:
|Plextor M8PeG||Plextor M8PeY|
|Controller||Marvell 88SS1093 (8-Channel)|
|DRAM||512MB LPDDR3 (1024MB variant)|
|Capacity||128 GB, 256 GB, 512 GB|
|NAND||Toshiba 15nm Toggle 2.0 MLC|
|Form Factor||M.2 (80 mm)||PCIe card (HH, HL)|
|Interface||PCIe 3.0 x4|
So what did Computer Base have to report with their hands-on preview of the new drive? Here's their CrystalDiskMark result:

Naturally we'll have to wait for a full-scale AllynReview™ to get a better idea of performance in all situations, but until then it's good to know we'll soon have another option to consider in the M.2 SSD market. As to pricing, we don't have anything just yet.

ADATA has been showing off some upcoming products at Computex, and it's all about DRAM.
We'll begin with an upcoming line of PCIe Enterprise/Server SSDs powered by the SandForce SF3700-series controller. We've been waiting for products with the SF3700 controller since January, when ADATA showed a prototype board at CES, and ADATA is now showcasing the controller in the "SR1020" series drives.
The first is a 2TB 2.5" drive, but the interface was not announced (and the sample on the floor appeared to be an empty shell). The listed specs are performance up to 1800MB/s and 150K IOPS, with the drive powered by the SF-3739 controller. Support for both AHCI and NVMe is also listed, along with the usual TRIM, NCQ, and SMART support.
Another 2TB SSD was shown with exactly the same specs as the 2.5" version, but this one is built on the M.2 spec. The drive will connect via 4 lanes of Gen 2 PCI Express. Both drives in ADATA's SR1020 PCIe SSD lineup will be available in capacities from 240GB - 2TB, and retail pricing and availability is forthcoming.
Continuing the DRAM theme, ADATA also showed new DDR4 modules in commodity and enthusiast flavors. Both of the registered DIMMs on display (an ultra-low profile DIMM was also shown) had standard DDR4 specs of 2133MHz at 1.2V, but ADATA also showed some performance DDR4 at their booth.

We know that SSD's help any system perform better by reducing the storage bottlenecks we all experienced from hard disk drives. But how far can flash storage go in increasing performance if money is no object?? Enter the multi-million dollar world of supercomputers. Historically supercomputers have relied on the addition of more CPU cores to increase performance, but two new system projects funded by the National Science Foundation (NSF) will try a different approach: obscene amounts of high-speed flash storage!
The news comes as the NSF is requesting a cool $7 billion in research money for 2015, and construction has apparently already begun on two new storage-centered supercomputers. Memory and high-speed flash storage arrays will be loaded on the Wrangler supercomputer at Texas Advanced Computing Center (TACC), and the Comet supercomputer at the San Diego Supercomputer Center (SDSC).
Check out the crazy numbers from the TACC's Wrangler: a combination of 120 servers, each with Haswell-based Xeon CPU's, and a total of 10 petabytes (10,000TB!) of high performance flash data storage. The NSF says the supercomputer will have 3,000 processing cores dedicated to data analysis, with flash storage layers for analytics. The Wrangler supercomputer's bandwidth is said to be 1TB/s, with 275 million IOPS! By comparison, the Comet supercomputer will have “only” 1,024 Xeon CPU cores, with a 7 petabyte high-speed flash storage array. (Come on, guys... That’s like, wayyy less bytes.)

The supercomputers are part of the NSF's “Extreme Digital” (XD) research program, and their current priorities are "relevant to the problems faced in computing today”. Hmm, kind of makes you want to run a big muilti-SSD deathwish RAID, huh?
Introduction, Design, User Interface
This summer is shaping up to be an amazing time to buy a gaming laptop. Intel has launched its Ivy Bridge processors, bringing faster performance to the entire range without increasing power consumption. Nvidia’s new Kepler based parts, although technically launched a couple months ago, are only now widely available.
We’ve already looked at many low-end solutions including Trinity, HD 4000 and the Kepler-based Nvidia GT 640M. We’ve also looked at one high-end gaming solution in the form of the ASUS G75V.
Today we're reviewing the Origin EON17-S, an obvious competitor to the G75V. It's packing an Nvidia GTX 675M. An Intel Core i7-3920XM joins the party as well. Clearly, this laptop is meant to provide maximum performance - as the other specifications make clear.
Though it has gobs of high-performance hardware our review unit did not arrive with an internal optical drive (it did come with an external Blu-Ray). The drive had been removed and a 1TB hard drive installed in its place. This is a clever bit of packaging that makes a lot of sense and isn’t offered by Alienware, Maingear or ASUS. While I know some gamers do still use optical drives, I personally can’t remember the last time one was required for install.
Our review unit tallies up at about $3500 bucks, which is expensive but not outrageous. Spending much more is difficult and requires that you either pony up for every frivolous option available or buy Nvidia Quadro graphics cards instead of the consumer-market GTX. Or you can put the price in reverse by downgrading to a Core i7-3610QM, which saves you over $1000.
